Thank you Watermans once again! I have been using your shampoo and elixir since beginning February and have some new regrowth and better quality hair (had a set back after using Olaplex No. 3 in June and lost a load of hair sadly) but it is gradually returning to how it was I think albeit slowly.
Using these fibres to hide the bald spots. Work amazingly well and gives me comfort to know I can hide that bald bits at the back while the shampoo and elixir are doing their thing.
Also on the vitamins now so hope to see even more results in the months to come.
Please don't change any of your range. You're saving peoples' self esteem which is one of the biggest achievements you could ever accomplish in life.
I will never stop using your products they have given me hope when I was at rock bottom before.
Am a hairdresser, bought this for my friend this as brought her confidence back as thinning hair on top easy to use thickness the hair up on top this is a excellent product would highly recommend thank you.
Great stuff. People are amazed that my thinning hair and bold spots litterally dissapear.
Excellent product for men/woman looking to cover thinning areas of hair. Gives you confidence back!!
I recently purchased the Hair Building Fibres- Dark Brown and I am thrilled with the results. Due to my thinning line I was looking for something to give my hair a thicker appearance. With just a shake of this magic powder my scalp is no longer visible and the colour is the perfect match too. I simply sprinkle along my parting and set with spray. It stays put until the next time I wash my hair and leaves no nasty residue. I have recommended this product to my sister and will continue to use it.
Thank you Watermans for restoring my self confidence :-)
My hair is so thin but it looks so different when I use this product. Can highly recommend
After being peri menopause for a few years and thinning quite a bit because of it! This gave me a real confidence boost!
Absolutely fantastic product! Just what I needed for my thinning hair. It covers very well, looks natural and easy to use. Excellent results and highly recommend.
Hair Building Fibres 23g Dark Brown - Hair Loss Concealer - Cover the gaps
I've been using Instahair for quite a few weeks. It's easy to apply and easy to wash out. My parting now looks normal and thinning hair isn't visible especially under bright light. An unexpected bonus is that Instahair helps to absorb natural oils so if I haven't time to wash hair, it doesn't look greasy. I recommend Instahair for anyone with thinning hair who needs a boost of confidence. Good price too!
I bought this for my husband, he is balding on top of his head and I know it really bothers him. This is great he puts a little bit on (he has dark brown and grey hair) and it does wonders it looks thicker and the thinning bald bit isn't notable. Really gives him confidence.
Really please with the results so far a good price for an amazing product . Only one that’s ever worked for me tried so many . Thanks
Does exactly what it says would recommend it to everyone.
Very natural
I was amazed how easy this was to use and it really does fill thinning Hair
Product is the best I have used, worth every penny. Thinning hair around my hairline after having a baby and this is my go to product. Also highly reccomend the shampoo and conditioner for hair loss and thinning hair after child birth. Been using the products since October 2018. Amazing!
Does exactly what it says and stays on for ages
I ❤️❤️❤️this product.. so ridiculously easy to apply and does exactly what it says on the tin!
Excellent product
Not only did it thicken my hair, it covered my grey roots. Great stuff

InstaHair Hair Building Fibres Dark Brown 23g - Hair Loss Concealer
First time I have tried this product. Very easy to use - just sprinkle it where needed and it makes hair look thicker until next wash. Will be buying more.
I buy the shampoo and when I noticed the new insta hair fibres I bought it straight away and omg it is amazing, I am nearly fifty and have noticed my hair thinning at the front which makes me so conscious that other people notice too, this product is fantastic and I feel so much more confident and it is so affordable I will be stocking up, thank you Waterman’s
I’ve used many brands of fibres in the past and this one is my favourite so far for covering bald patches (look as natural as possible). However, it builds up and then sits above the root and forms visible clumps, which tend to drop off on to face and clothing
I brought this product as a trial but honestly didn't expect it to work but I was very long. I use this on my crown and honestly once applied it looks like I have never had a thicker head of hair!
I can’t believe how good it is
Confidence through the roof
Very good product does what it says
Please ask me later about the hair fibre product . I have only used it once but it really worked for me and I’m sure it’s going to prove as wonderful as all your other products.
I love the shampoo and conditioner also the serum. Thanks Waterman’s....
